How would I be able to make an update system for my plugin?

[Micamaster100 (M100)]

I have realized that Moon Animator and F3X Have a way of detecting if there is a newer version of their model/plugin. How do they do this, and how can I make an update system myself?

They store the version as a variable and save the current version on the Description and then use MarketplaceService:GetProductInfo(id).Description to match the versions.

	local ver_check = pcall(function()
		local verCheck = game:GetService("MarketplaceService"):GetProductInfo(id).Description
		if verCheck then
			local _, checkVer = string.find(verCheck, "!V")
			if checkVer then
				local theVer = tonumber(string.sub(verCheck, checkVer + 1))
				if theVer > _g.ver then
					ver_ui.Label.Text = "v"..tostring(_g.ver).." [OUT OF DATE, NEW v"..tostring(theVer).."]"
					ver_ui.Visible = true
				end
			end
		end
	end)
